Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516886, here are decompositions:

  • 3 + 516883 = 516886
  • 47 + 516839 = 516886
  • 173 + 516713 = 516886
  • 197 + 516689 = 516886
  • 233 + 516653 = 516886
  • 263 + 516623 = 516886
  • 269 + 516617 = 516886
  • 347 + 516539 = 516886

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 516,886 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 516886 first appears in π at position 77,417 of the decimal expansion (the 77,417ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
